I lose my keys all the time. I’m not sure how but it happens. Considering there are six people living in my house, if we believe a key has fallen into the wrong hands, hiring a locksmith to change the locks is a chore. But, alas, no more! We can leave the house without our keys thanks to iQBio’s fingerprint-scanning door lock.

We no longer have to worry about carrying our keys on us when we go out for a morning jog. We can easily add our friends’ fingers to the Guardian XL’s database so we don’t have to worry about keeping track of lender keys. Even my mother can come over whenever she wantsit doesn’t matter if I’m not home from work yet.

But perhaps most importantly, it looks awesome and is fun to use. Who’s going to break into a house with a doorknob looking this sophisticated? A crazy man, that’s who. Fortunately this lock is significantly better built than our old one so it’s going to take that maniac a whole lot of work to get inside. However, our TV-viewing informs us that no biometric device is fool-proof. Fortunately, the optional password option on the Guardian XL compensates by requiring users to type in a secret code before entering.

In the time it would take me to find my house key and unlock the door, I’m already inside and half-way down the hall with my biometric door lock. So if you can afford the required cash to switch out a front or back door with a biometric reader, the iQBio’s Guardian XL is an excellent way to go. You’ll get peace of mind and one less thing to keep in your pocket.
